N2  - Experiments were conducted in a Striga-sick plot for three seasons (1998-2000) in Medani to evaluate maize (Zea mays L.) genotypes for Striga hermonthica resistance. A total of 327 genotypes were tested. Striga population, grain and straw yield were used to evaluate Striga parasitism. Days to 50% silking, Striga counts, grain and straw yields were significant (P<0.05). In the first season (1998), the best local variety Kadogli gave straw yield of 6,902 kg/ha; hybrids S-97206-24 (9,816 kg/ha) and S-97206- 30 (9,462 kg/ha ) were tolerant to Striga. During 1999 season, genotypes KB98B-98203-10 (1,725 kg/ha), TZLCOMP11-WC4 (1,572 kg/ha) and KBO98B-98204-7 (1,570 kg/ha) showed relative tolerance to S. hermonthice. Mugtama-45, a local check, gave grain yield of 1,225 kg/ha. While in the 2000 season, Striga infestation was generally low. Genotypes EM99B-99225-5 (3,063 kg/ha), EM99B-99225-7 (3,047 kg/ha), and EM99B-99225-14 (3,032 kg/ha) were identified as high yielders. Mugtama-45 had grain yield of 1,734 kg/ha. Good performance of genotypes during the 2000 season may be attributed to low Striga infestation as shown by Mugtama-45 with an increase of 42% in grain yield over the 1999 season. In all the seasons, relative tolerance of some genotypes was evident but Striga population was not consistent with grain and straw yields
